Describe the bug
The command is printed but doesn't seem to be actually sent to tmux, for example the command ssh user@host is shown on the screen in the tmux session but no ssh command is run

To Reproduce

name: project
root: ~/
windows:
  myhost:
    -  ssh user@myhost

Expected behavior
The ssh command to be executed in the tmux window
